This problem mostly caused by memory or memory installation. Our boards and servers have all gone through intensive tests before they made it to consumers. If you run into this problem, please follow the steps below:
1. Remove the board from the chassis and set it on a test bench with sufficient power supply, monitor, 1 CPU, and 4 pieces of recommended memory on a memory card.
2. Make sure that you install memory modules correctly on the board, i.e. 2 pieces on each column that is closest to the golden fingers (check manual).
3. Once you install the memory card onto the motherboard, make sure that it is all the way in.
